"All the Real Math To Which School (Including College) Refused Yo u Access."
by voiklis＠redfigure.org 05 May '03

05 May '03

It is an imagined book; both one that I can imagine creating and one which I often imagine that I need. For example, I easily set up the 2nd order differential equation and, with a bit more effort, recalled enough trig to figure out and tinker with the pendulum example project, but "weighing" the forces at different angles has kept me stumped for the last couple hours (playing with my children HAS pleasantly distracted me somwhat). In my experience, limited understanding of real-world math and its applicability across disciplines is what has prevented the effective use of computing (especially as a means of modelling, manipulating, and understanding real-world phenomenon) in schools and throughout the culture. BTW: The the pendulum project Alan sent out will open in the Squeak.org version of Squeak. I have to go to work now, so I cannot look into the incompatibility issue at this time; there are plenty of people on this list who could debug it faster and more reliably than I.

etoy issues/making games and mazes
by Kim.Rose＠viewpointsresearch.org 05 May '03

05 May '03

-- Hi, In repsonse to recent email queries about making mazes/and creating scripts with feedback, I direct you to the "project swiki" that is part of the Squeakland site: http://www.squeakland.org:8080/super/gallery If you specifically check out the "Robot car in Maze" and "Sensor Car" projects you can see by using a conditional/test tile and the "color sees" tiles you can make a simple feedback script by just using "forward by" and "turn by" tiles. What's great in this kind of project is the kids need to think about the direction of their object's heading and if the object needs to turn left or right to keep on the course and therefore they need to think about using positive or negative numbers. This is very simple and does not even require thinking about x or y coordinates. (We introduce that later.) The kids LOVE making all kinds of variations of mazes and games. By the way, *any* of you can and are welcome to publish/post your examples to this Project Gallery/Swiki. To do this, hold down the "Publish" button on the gold navigator bar and select, "Publish to another server". After you have named the project you wish to share, you'll get a directory in a blue window. Selecting "Squeakland BSS" will publish your project to this page on the Squeakland site. We'd love to see more examples here! I hope these examples help! have fun, Kim

Pendulum

Andreas/Phil, Wouldn't another possilble approach be to create a series of pictures showing all the possible positions of the pendulum and then control it as one would control a cartoon/movie? (Phil - There are examples of this technique at squeakland.org under the eToys link.) Another option that comes to mind is to stack each of these pictures on top of each other and move them front to back as required. Andreas, I'm new to Squeak -- would these ideas work, or am I on the wrong track? Thanks, Bruce Strothenke Teachers College Columbia University

Best supported platform for Squeak?
by David.Mitchell＠mail.sprint.com 18 Apr '03

18 Apr '03

The fact that Squeak is open source doesn't necessarily mean it is best supported on an open source OS. Squeak was originally written for MacOS. The Unix and Windows ports were/are largely the efforts of Ian Piumarta and Andreas Raab, respectively. I've been running Squeak since 1998 on various flavors of Windows, MacOS 8-X, and a few Linuxes. Most of my Squeaking is done on Windows, because I usually use Windows at work. I've had the least trouble with Squeak on Windows, but that is probably mostly due to my familiarity with the platform. Of course, Squeak works marvelously in a blended environment. I went to the first CampSmalltalk back in 2000 and we we regularly shared code and images across platforms. Other platforms (handhelds, etc.) will run Squeak, but not usually with all of the bells and whistles expected by a squeakland user. (3D support and sound spring to mind). -- David Mitchell david.mitchell(a)mail.sprint.com -----Original Message----- From: Jim Ford [mailto:jaford@watford53.freeserve.co.uk] Sent: Thu 4/17/2003 3:07 PM To: Squeakland Cc: Subject: Best supported platform for Squeak? Hi, I use Linux by choice, but still need WinME for Photoshop and others. I have a twin 400MHz Celeron setup and whilst WinME only recognises one processor, it still feels that it runs faster than under Linux with a SMP kernal that recognises both processors. I feel that Squeak, being open source, ought to be best supported under Linux, but wonder if in fact this is not the case. Comments, anyone? Regards: Jim Ford

Anyone seen Croquet working?
by jaford＠watford53.freeserve.co.uk 18 Apr '03

18 Apr '03

Hi, Croquet looks very interesting, but I've not had any luck getting it running. Under Windoze ME the VM crashes with the following messages - 'Exception Code : C0000005, Exception Address: 862797F8, Current Byte Code: 160, Primitive Index: 117'. I've tried running it under Linux by passing the Croquet image to Squeak, but I get the message that my platform is not recognised. Ideas, anyone? Regards: Jim Ford

Archived version of Papert/Kay talks
by darius＠inglang.com 18 Apr '03

18 Apr '03

Dr. Seymor Papert seemed to cut his talk short at OISE due to time constraints. Does anyone know what he intended to cover at the end of his talk? Cheers, Darius -- Hi, folks - I know many of you hope to view the "Papert/Kay talks" delivered by Seymour and Alan at OISE in Toronto on February 27th from an archived file on the Web. We've just checked status on the availability and here is the info I received: The technical aspects are being completed now and it should be up before the end of the week. It will be posted to the Fields website at http://www.fields.utoronto.ca/programs/mathed/ So, if you are interested, I suggest you check this url the first part of next week. Happy viewing! Kim

Pendulum

One of my colleagues is doing a pendulum study in her 5th grade classroom. I thought it would be interesting to do a Squeak project about pendulums. This is as far as I've gotten...I'm not sure how to make the pendulum swing while it's fixed point stays attached to the blue block. Any suggestions? Phil

Thanks! I agree with your points. By the way, am gearing up to use Squeak in a couple of NY city schools - will keep you posted. Bruce

And although I haven't tried "stacking" a number of pictures on top of each other, I did notice in our recent workshop that "send to back (or front)" is an included feature. Couldn't that be scripted to show motion? Bruce
